The artist looks to be Van Hier - going mostly by the signature (full name Joachim Van Hier - he had a few aliases as well such as Joachim Hierschl-Minerbi). He was born in Trieste in 1834 (although is considered Austrian). I couldn't find a reference to this particular painting (but he has done some paintings of a similar style to this and several on the same sort of subject).
